Method and device for testing extraction load

摘要

A method and device for objectively determining extraction loads for, or verifying capability to withstand loads for fasteners, sealants, or overlying materials attached to an underlying material. The method provides for a repeatable and objective test for comparing extraction load and load bearing capability of fasteners, sealants, or overlying materials attached to an underlying material to standards for the same. The portable device provides for testing various types of fasteners, sealants, or overlying materials attached to an underlying material in a repeatable and easily usable manner. The device comprises a means of generating, applying, and measuring load forces, and providing the data therefrom.

主权项

1. A device for measuring an extraction load comprising:
a. a base adapted to be supported by an underlying material, wherein the base comprises:
(i) a device platform; and(ii) a plurality of legs attached to the device platform; andwherein the base provides a stable foundation to test a fastener or an overlying material attached to the underlying material; b. an extraction load generator supported by the base; c. an extraction load applicator in contact with the extraction load generator, wherein the extraction load applicator transmits a load generated by the extraction load generator to the fastener or the overlying material, and wherein the extraction load applicator comprises a plurality of interchangeable attachments for connecting to different types of fasteners or for connecting to different types of overlaying materials; and d. a means for measuring the load generated by the extraction load generator.
